Pulp gas-water separation device for papermaking field on basis of centrifugal force principle

Abstract

A pulp gas-water separation device for the papermaking field on the basis of a centrifugal force principle comprises a shell, a conveying pipeline and a conveying branch pipe, and the conveying pipeline is connected with a vacuum coated roller and connected with the conveying branch pipe. The conveying branch pipe is communicated with the bottom of the shell. The conveying branch pipe is communicated with an air distribution device at the bottom in the shell. A first baffle is fixedly arranged on the upper portion of the air distribution device, the first baffle is obliquely arranged toward the right upper portion, the left end of the first baffle is fixedly connected with the left side wall of the shell, and a gap is reserved between the right end of the first baffle and the shell. The device has the advantages that heating resistance wires are specially buried in the first baffle and a second baffle to make gas and water smoothly separated and steam containing slurry continues keeping the vapor state; surface tension of the slurry is large, so the slurry in the steam can be left on the surface of the first baffle and the surface of the second baffle and left along baffle surfaces with certain inclination angles, and primary separation of the steam and the slurry is achieved.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a pulp air-water separation device for papermaking based on the principle of centrifugal force. Background technique [0002] Paper is the most commonly used item in our daily life. Whether we are reading, reading newspapers, writing or drawing, we have to come into contact with paper. In the production of industry, agriculture and defense industry, paper is also inseparable. Today, it is simply unthinkable without paper. Paper is a powerful tool and material in exchanging ideas, disseminating culture, developing science and technology and production. Looking back at history, this important substance was invented by the working people of the Han nationality in ancient China. Papermaking, compass, gunpowder, and printing are known as the four great inventions of ancient Chinese science and technology, and they are outstanding contributions made by the Chinese people to the ...

Problems solved by technology

Currently in the industry, the slurry in the vacuum-covered roll contains a large amount of water vapor, and the slurry containing water vapor will bring noise and huge energy consumption to the downstream equipment. Therefore, how to remove the slurry from the vacuum-covered roll The water vapor in the pulp has always been a technical problem that plagues the pulping industry
